At 40A with a B curve characteristic it is typically used on cookers, electric showers and EV charger supplies. Final device selection should always follow the circuit design, cable size, installation method and fault level of the installation.\u003c\/p\u003e\u003ch2\u003eKey features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e40A rated current, B curve characteristic\u003c\/li\u003e\n\u003cli\u003e30mA Type B residual current protection\u003c\/li\u003e\n\u003cli\u003e6kA breaking capacity\u003c\/li\u003e\n\u003cli\u003eProtects against overload, short circuit and earth leakage\u003c\/li\u003e\n\u003cli\u003e1P+N with switched neutral\u003c\/li\u003e\n\u003cli\u003eDesigned for FuseBox consumer units\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eSpecifications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e FuseBox\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct code:\u003c\/strong\u003e RTB06B40BD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct type:\u003c\/strong\u003e RCBO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRated current:\u003c\/strong\u003e 40A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTripping characteristic:\u003c\/strong\u003e B Curve\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRCD type:\u003c\/strong\u003e Type B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRated residual current:\u003c\/strong\u003e 30mA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBreaking capacity:\u003c\/strong\u003e 6kA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConfiguration:\u003c\/strong\u003e 1P+N switched\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting:\u003c\/strong\u003e 35mm DIN rail\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard:\u003c\/strong\u003e BS EN 61009-1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eSuitable for\u003c\/h2\u003e\u003cp\u003eDomestic consumer units, rewires and RCBO board upgrades.
